  1. 1. Retinal glucose metabolism and blood flow : Effects of photic stimulation

    Författare :Lin Wang; Uppsala universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Physiology and anatomy; blood flow; darkness; flicker; glucose oxidation; glycolysis; lactate; light; nitric oxide; optic nerve; retina; Fysiologi och anatomi; Physiology and pharmacology; Fysiologi och farmakologi; Physiology; fysiologi;

    Sammanfattning : Retinal glucose metabolism was investigated under different light conditions in cats,pigs and rabbits. Glycolysis and glucose oxidation in the outer and inner parts of theretina were assessed by determining arteriovenous concentration differences foroxygen, glucose and lactate, as well as local blood flow.

  3. 2. The neuromodulatory effect, safety and effectiveness of vagus nerve stimulation

    Författare :David Revesz; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Vagus nerve stimulation; VNS; Neuromodulation; Neurogenesis; VBLOC; Epilepsy; Depression; Safety; Efficacy; Effectiveness;

    Sammanfattning : Vagus nerve stimulation (VNS) is an adjunctive palliative neuromodulatory treatment for drug resistant epilepsy (DRE) and chronic depression. It has also been proposed as a treatment for many other conditions such as chronic pain, heart failure, and Alzheimer’s disease. LÄS MER

  5. 4. Upper and Lower Motoneuron Lesions in Tetraplegia - Diagnostic and Therapeutic Implications of Electrical Stimulation

    Författare :Ines Bersch; Göteborgs universitet; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Electrical stimulation; Tetraplegia; Upper motoneuron lesion; Lower motoneuron lesion; Motor point topography; Nerve transfer;

    Sammanfattning : The overall objective of this thesis was to improve outcomes and predictability of the treatment of upper extremity function in patients with cervical spinal cord injury and tetraplegia by advancing the diagnostic and therapeutic tools employed in upper and lower motor neuron lesions. An overview is presented of the current knowledge about the principles of electrical stimulation and its usefulness and proven effects on the upper limb. LÄS MER

  7. 5. Computational Models in Deep Brain Stimulation : Patient‐Specific Simulations, Tractography, and Group Analysis

    Författare :Teresa Nordin; Karin Wårdell; Simone Hemm-Ode; Johannes D. Johansson; Harith Akram; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anisotropy; Deep brain stimulation DBS ; Finite element method FEM ; Patient‐specific simulation; Probabilistic stimulation maps PSM ; Tractography;

    Sammanfattning : Deep brain stimulation (DBS) is an established method for symptom relief in movement disorders like Parkinson’s disease, essential tremor (ET), and dystonia. The therapy is based on implanting an electrode with four contacts in the deep brain structures where it provides electrical stimulation, mainly impacting the nerve tracts. LÄS MER
